Preparative Pump 1800
Replacement for the older K-1800, this superbly rugged,
dual piston pump is perfect for prep and semi-prep applications,
but is even accurate at analytical flow rates. ( 0.1 - 1,000
mL / min). This is the pump of choice for many SMB systems,
and is embedded in some commercial prep HPLC systems.
The Preparative Pump 1800 is a versatile HPLC pump with an interchangeable
pump head available in different sizes and materials, including
non-ferrous, biocompatible versions. Up to four pumps can be used
to create a high pressure gradient system. This pump can also be
used to form reliable and reproducible gradient profiles when equipped
with the optional low pressure gradient valve module which is easily
mounted in front of the pump head.
